Patented Sept. 2, 1930 PATENT OFFICE HENRY PALIFERRO, OF CHICAGO, ILLINOIS nnm-Lacme VISE Application filed Augusto, 1928. Serial No. 297,888.

This invention is a belt lacing vise, and the object is to provide a vise in sim le, practical and durable form, adapted or facilitating the operation of lacing together the 6 ends of machine belts.

In the drawing Figure 1 is a front side elevation; Figure 2 is a top plan View; Figure 3 is a rear side elevation; 1 Figure 4 is an end view showing the device in use; Figure 5 is a detail of the knife crank; Figure 6 is a detail of a form of insertible punch block attachment; Figure 7 is a detail of the punch and die assembly for punching holes in the belt ends for cord lacing the ends together, the belt ends'being shown in position for punching the holes' therein Figure8 is a detail of the lace or clip holder.

Figure 9is adetail edgeview of the ends of a beltlaced together and with the per manent lock pin in place.

The invention includes a base plate 1, having a back late 2 rigidly mounted at one side thereof An angular edged slide or guide 3 is rigidly extended medially and transversely over the plate 1. A pressure plate 4 is provided of substantially the same dimensions as the plate2, but bein cut away at its lower corners to form he t-ways 5. The resulting medial tongue 6 is mortised at 7 to slidably engage the slide or guide 3. A

vise screw 8 is journaled at 9 through the front plate 4 andpasses through the back plate 2 in threaded engagement therewith as shown at 10, in a conventional manner.

A steadying pin 11 is anchored in the upper portion of the front plate 4 and passes slidably through the back plate 2. Clip holder recesses 12 are formed horizontally in the inner faces of the plates 2 and 4 at the right hand sides of thosefaces, there being ali ned guide pin holes 13 pierced through the p ates at either end ofthe recesses 12. A clip holder 14 is provided, the same being in the nature of an-elongated rectangular frame open clear through and having its side strips beveled off or flared outwardly from a central longitudinal line 25 at each side, so as to form upper and lower V-shaped clip seats 15 and 16 within whiclr'may be conveniently positioned a plurality of V-shaped metal lac ing clips 17 turned upwardly and 18 turned downwardly.

A ke pin 19 is slidably insertible through the en s of the holder 14 and passing under the bight portions of the clips, serves to retain the same in proper position relative to the holder 14. This'key' pin may be pulled out for the insertion of clips in the holder, after which the pin is inserted as stated. Guide pins 20 extend laterally at either end of the holder 14 and slid'ably passing through 66 the holes 13 in the plates 2 and 4, serve to v maintain the holder 14 in proper horizontal alignment with the recesses 12, into which recesses the holder 14 is adapted to recede as the plates 2 and 4 are pressed together. In the operation of the device sofa; as described, the holder 14 is filled with clips 1:7 18, turnedf upwardly and downwardly and alternately arranged with their bights overlapping as shown in dotted lines in Fig- 7 ures 1 and 3 and in full lines in Figure 4. The upper and lower belt ends 22-23 are then passed between therplates 24 as shown in Figure 4, and into the spread clips 1718. The screw 8 is then turned by the handle 24 which presses the plates 2-4 together in vise-like manner upon the open clips, forcing the'jaws of the clips into the belt ends, thereby'firmly connecting these ends. The vise plates 2 and 4 are then loosened from $5 the belt ends, the belt, and holder 14 are removed, and the key 19 is .ulled out of'the holder and a permanent loo 1 pin 26 is inserted in lieu thereof through the overlapped: bights of the clips 17--18.

For squaring the ends of the belt, a cutter assembly 27 is mounted at the top of the plates 2 and 4. This assembly includes a gear shaft 28 j ournaled through the plates 2 and 4 at the left hand side thereof, one end of the said shaft having a. crank 29 and the opposite end being squared as shownat 30. A permanent gear 31 is rigidly mounted upon the handle end of the shaft 28, and an ad ustabIe gear 32 is slidably mounted upon the said 9 squared end 30. Rack bars 33, slotted longitudinally at 34, are slidably mounted upon guide studs 35 extended at the front and rear sides of the device from the plates 2 and. 4..

5 These rack bars 33 are provided with racks 36 at their lower sides at one end, which are placed in mesh with the gears 31-32. A. bracket 37 serves to hold the adjustable gear 32 upon the squared end 30 of the shaft 28.

m A cutting knife 38 has its shank rigidly inned at 39 to the rear. rack bar 33 and overies the top of the two lates 2 and 4. To squarethe end, say of t e belt end 23, it is simply drawn up between the plates 2 and l w and gripped by the said plates with the upper end of the belt slightly projecting above the said plates. Then by turning the crank handle 29, the knife 38 is made to cut off the belt end squarely The process is then repeated 2% upon the other belt end. The front plate 4 is mortised out at the left side upon its inner face, as shown at 40 and a punch block 4-1 is slidahly inserted therein. This block is provided with two upperand two lowerpunches 25 42v Die holders 43 are formed in the back late 2 in alignment with the punches 42. A

elt holding; spring 44: is seated below the punches 42. Means are thus provided for punching holes in the belt ends 22 and 23,

where it is thought desirable to use cord lacings in lieu of the metal clips 17 -18.

While I have herein described a certain specific manner and method of constructing and assembling the elements of my invention,

w it isunderstood that I may vary from the same in minor details, not departing from the spirit of my invention, so as best to construct a practicaldevice for the purpose intended, as defined in the appended claim.

In a device of the kind described, a pair of Flat plates arranged as a vise, the same having transversely aligned recesses formed therein, a clip holder reniovably seated within said 45 recesses, means for releasably mounting belt clips in the said clip holder, and a. cutting knife mounted upon the said plates and movable across the upper ed es thereof.
